Learning Webservices

I am trying to learn webservices and very much confused where to start from, I started with the oracle docs and could not concentrate much on it i feel the docs are very dry for a newbie, Can anyone suggest me a user freindly book like servlets and JSP by Cathy. Any tutorial or any pdf. I dont even know what to start with either JAX RPC or JAXWS

Thanks,

JAX-RPC is dead; don't even read up on it. JAX-WS (for SOAP-based WS) and JAX-RS (fro RESTful WS) are the APIs to use these days. Start reading here: https://www.coderanch.com/how-to/java/WebServicesFaq
